Inconel 800/825 Sheets & Plates

What are Inconel 800/825 Sheets & Plates?

Inconel 800 (UNS N08800) and Inconel 825 (UNS N08825) are nickel-iron-chromium alloys designed for excellent strength and corrosion resistance.

• Inconel 800 is ideal for high-temperature applications requiring resistance to oxidation and carburization.
• Inconel 825 offers enhanced corrosion resistance in acidic environments due to the addition of molybdenum and copper.

Key Functions:

• Withstand high temperatures and thermal stress
• Resist oxidation, scaling, and corrosion
• Perform in acidic and chemical environments
• Ensure long-term durability and reliability

Chemical Composition of Inconel 800/825

Inconel 800 (UNS N08800):

• Nickel (Ni): 30% – 35%
• Chromium (Cr): 19% – 23%
• Iron (Fe): Balance

Inconel 825 (UNS N08825):

• Nickel (Ni): 38% – 46%
• Chromium (Cr): 19.5% – 23.5%
• Molybdenum (Mo): 2.5% – 3.5%
• Copper (Cu): 1.5% – 3.0%
• Iron (Fe): Balance

The addition of molybdenum and copper in Inconel 825 significantly improves resistance to acids and corrosion.
